Thinking of getting one of these but not sure how it works with the 4 stages. Are the 4 different stages automatic or selectable? Also noticed in pictures of these that it has a button on either side. Are these switches that depress when the lid is closed? Thanks
Charging process
Stage 1 – Automatic analyzing battery status
Stage 2 – Quick charge
Stage 3 – Slow charge
Stage 4 – Standby mode, trickle charge
